How To Install Ductless Heating And Cooling Systems

To install ductless heating and cooling systems is very simple using a mini-split system. In this article, we’ll show you how to do it yourself. First we will start by identifying tools required. How to Reset DStv & fix Dstv channels not showing

Required Tools To install ductless heating and cooling systems

  1. Adjustable wrench
  2. Drill/driver
  3. Hole saw
  4. Level

However, you will be needing the following materials; Condenser wall brackets, Ductless mini-split system, Plastic condenser pad, Plastic line set cover kit

Installing an A/C system always sound like a big deal. Although, this is not far from the truth. While it may be true,  a novice and a non-pros installed this ductless “mini-split” system in a hotel one day.

In fact, the installation was simple because of the special line set. It always comes prefilled, or “precharged,” with refrigerant and also connectors that don’t need special skills or tools. All you need to do is just to mount the two main units and then connect the line set to the condenser. Already,  Some mini-splits include an easy-install line set, but some don’t.

Of course, a mini-split system can be installed in an personal office, rest room, a cabin or a shed. Moreover, Some offer heating as well as cooling, in the same vein, some include multiple evaporators to serve multiple rooms. Although it Depends on features and size, most DIY mini-splits cost from $700 to $2,000. How to Hard Reset Your DISH Network Receiver

Choosing the system

Only few brick-and-mortar stores carry DIY systems, online shopping may be your only option. Although, there are many online suppliers. The size of the system is given in BTUs (British thermal units). The higher the number, the bigger the cooling capacity. To choose the right size mini-split, calculate the heat loss of the room. Many websites already made these calculations simple. Don’t assume; an undersized system won’t keep up, and an oversized system will cycle on and off too frequently, shortening the condenser’s service life. A Climate Right 12,000-BTU heating and cooling system was installed and it costs about $1,100. The other necessary materials totaled about $275.

Below is a step by step guide to install a ductless heating and cooling systems at ease.


Step 1

Install the mounting bracket

Installing ductless heating and cooling systems

Fix the evaporator inside the room on an exterior wall ensuring it’s not on direct sunlight, Windows and sources of dust. Installing a home Air condition, have in mind that this area of the wall should be free of wires, pipes and ducts that would interfere with making a hole for the line set. Mark the stud locations and fasten the bracket to them with screws.

Step 2

Drill a 
pilot hole

Installing  Air condition system

The line set hole should slope slightly downward to the outside to condensate from the evaporator and can drain outside. Start by drilling a pilot hole from inside to outside. Ensure no trim or other obstructions will complicate drilling the required hole.

Step 3

Bore the full-size hole

Cut with a hole saw from inside, move aside any insulation and check the wall cavity for any obstructions. Finish up by drilling from the outside.

Step 4

Run the line set

Carefully uncoil the line set from the back of the evaporator. With an aid, feed the line set through the hole. As it emerges, the helper should easily bend the line set downward and to the side as required to reach the condenser. Always sleep the rigid plastic collar surrounding the line set at the end that connects to the condenser. The drain line is smaller and pass through last, below the other lines. Add the drain extension and wrap the joint with electrical tape to keep it intact.

Step 5

Install the evaporator


Wrap the foam sleeve within the section of line set within the hole and then replace any insulation in the wall cavity that was disturbed. Also hang the evaporator on the mounting bracket. Your helper may have to feed a few more inches of the line set outside as you do this. On the outside, put the two-piece plastic trim into the hole to avoid any rough edges from spoiling the line set.

Step 6

Install the condenser

Installing the condenser

Set the condenser on a pad on the ground or you can also mount it on a wall bracket so that the refrigerant lines can quickly reach it. Route the line set so it stays tight to the building exterior and doesn’t leapfrog any obstructions. This makes it easier to install a cover. Ensure the condenser has the recommended clearance from walls and bushes. When fixing A/C, Avoid placement where ice or packed snow could fall on it or where other appliances vent. A location on the east or north side of the structure might maximize the cooling efficiency.

Step 7

Connect the refrigerant lines

Connect the refrigerant lines

Although this step varies by manufacturer. Using this system, a locking lever presses the line connections together. Before powering up, check the refrigerant lines for kinks and then verify the electrical connections. And then go inside and set the temperature using the handheld controller.

Step 8

Cover the line set

Cover the line set

Cover the line set

Insulate and seal the hole in the outside wall, then cover the line set using sections of plastic or metal channel cut to length. Put the back half of the channel behind the line set, plumb it and anchor it to the wall using a self-tapping screws. Our line set travels horizontally to the compresser, so when we added the channel corner (see p. 46), we drilled a hole in it to allow the drain line to exit straight down.

How To Install Ductless Heating And Cooling Systems

A mini-split system has two main components: an indoor evaporator, that cools the air, and an outdoor condenser, which dissipates heat. They’re however connected by a line set, tubing that passes through a baseball-size hole in the wall, carrying hot refrigerant outside and cold refrigerant in. Our line set also included cable to power the evaporator and a drain line to carry condensation outside.
